Rhinoscopy is an examination of the nose. It is performed through two procedures:
What is anterior rhinoscopy?
The anterior rhinoscopy or fiberoptic is part of the medical examination in the clinic. It is done with an instrument called a nasal speculum. The doctor wore a headlamp to free his hands and shine light into his nose. The speculum is placed in the nostril to enlarge the nostril. Repeat the same operation for the other nostril. The pre-nasoscopy takes less than one minute. It helps to assess the condition of the nasal mucosa, secretions, the location of the nasal septum, foreign bodies, and the presence of abnormal growths and nasal masses. The anterior Fiberoptic can be performed with or without local nasal congestion.
What is a posterior rhinoscopy?
Posterior rhinoscopy is used to examine the structure behind the nose. The structures seen in posterior fiberoptic include the posterior end of the nasal septum, the posterior end of the turbinate (nasal bone), Rosenmuller’s fossa (a common site for malignant tumors), the opening of the Eustachian tube, and the upper surface of the soft tissue. Taste. It can be performed using a rear nasal mirror or a endoscope.
Rear fiberoptic with Mirror: The mirror is called the St. Clair Thompson’s Rear fiberoptic. Posterior rhinoscopy is a simple outpatient procedure that takes less than a minute and is part of the physical examination. The mirror is heated and inserted into the mouth, and the tongue is pressed with a tongue depressor. The reflection of the posterior nasal cavity falls on the mirror and the doctor examine it.
Posterior rhinoscopy with endoscope: Diagnostic endoscopy is a diagnostic medical procedure in which the internal structure of the nose and/or throat is examined. It detects and diagnoses abnormalities in the nasopharyngeal area. It is performed by a thin, rigid or flexible telescope sight with a camera (nasopharyngoscope).
The flexible nasopharyngoscope can be used to evaluate the nose and throat at the same time, while the rigid endoscope can only be used to evaluate the nose. Both rifle scopes have a camera and a light source. The camera is connected to the monitor to display the magnified video and the image captured by the camera. You can record the video for future reference. This procedure is performed by an ear, nose and throat surgeon (ENT doctor).
Some nasopharyngoscopes are also equipped with suction devices and tweezers (grasping instruments), which can be used to clean the nose, sinuses or throat and, if necessary, a biopsy (tissue removal).
This is usually an outpatient operation and usually only takes a few minutes. Use local anesthesia for the nose and throat to minimize discomfort. It can also be performed on children. Children may need mild sedation before surgery.
Nasopharyngoscopy helps ENT surgeons evaluate the nose, sinuses, and throat.
It may help evaluate the following conditions:
- chronic nasal congestion
- chronic sinusitis
- nasal polyps or abnormal nose growth
- nasal tumor
- nasal congestion
- foreign body in the nose or throat
- epistaxis (bleeding through the nose)
- vocal problems)
- obstructive Sleep apnea
- Speech disorder (dyspnea)
- Progression after nasopharyngeal surgery or medication
